COt) 0.3165 



o It will be assumed that, owing to the velocity of blast, the admixture of inert gases from zone* 

 below, and the low temperatures of zones above, this COt escapes reduction to CO. 



& It will be assumed, for the reasons stated under zone 570, that only j of the COi driven off here 

 Is reduced to CO in nppcr zone 57u.
